Switch on the ignition (page 39).
The tilt/sliding panel is opened and closed
electrically. The switch for the tilt/sliding
panel is on the overhead control panel.
The tilt/sliding panel only operates with
the roller sunblinds opened.
Warning!G
When opening or closing the tilt/sliding
panel, make sure that there is no danger of
anyone being harmed by the opening or
closing procedure.
The opening procedure of the tilt/sliding
panel can be immediately halted by releas-
ing the switch or, if the switch was moved
past the resistance point and released, by
moving the switch in any direction.
The closing procedure of the tilt/sliding
panel can be immediately halted by releas-
ing the switch.
The panorama roof with power tilt/sliding
panel is made out of glass. In the event of
an accident, the glass may shatter. This may
result in an opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts
properly as entire body parts or portions of
them may protrude from the passenger
compartment.
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle.
Unsupervised use of vehicle equipment can
cause an accident and/or serious personal
injury.
!To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding panel.
Do not open the tilt/sliding panel if there is
snow or ice on the roof, as this could result in
malfunctions.
iWhen the tilt/sliding panel is open,
resonance noises may result in addition to the
usual wind noises. They are caused by minimal
pressure changes in the passenger compart-
ment. To reduce or eliminate theses noises,
change the position of the tilt/sliding panel or
open a door window slightly.
iYou can also open or close the tilt/sliding
panel using the SmartKey or the KEYLESS-GO*
function, see “Summer opening feature”
(
page 254) and “Convenience closing
feature” (
page 256).
iThe tilt/sliding panel may also open when
using the air recirculation button:on the
control panel of the climate control
(
page 220) or automatic climate control

Driving systems
Basic settings (except R 63 AMG)
There are two settings from which to
choose:

Raised level, for driving on rough roads

Highway level, for driving on paved
roads in fair or better conditionThe vehicle’s ride height changes by the
approximate values given in table below
according to the set level:
The vehicle lowers to highspeed level
automatically when

the vehicles speed exceeds
70 mph (112 km/h)

the vehicles speed is between
60 mph (96 km/h) and
70 mph (112 km/h) for longer
than 20 seconds
Warning!G
Make sure that no one is near the wheel
housing or under the vehicle when you lower
the vehicle while it is standing still. Limbs
could become wedged into or under the
vehicle.
For safety reasons, the vehicle can only be
lowered with all doors and the tailgate
closed. Lowering is interrupted if a door or
the tailgate is opened and will continue after
the door is closed again.
Warning!G
Adapt your speed and driving to possible
changed driving behavior of the vehicle after
changing the vehicle level. The ESP
® cannot
prevent accidents, including those resulting
from excessive speed. The ESP
® cannot
prevent the natural laws of physics from
acting on the vehicle.
!Keep in mind that in rough or uneven roads,
adjusting the vehicle to a lower level may cause
the vehicle underbody to come in contact with
the road and result in damage to the vehicle un-
derbody. Always make sure the vehicle has suffi-
cient ground clearance before adjusting it to a
lower level.
!Before jacking up the vehicle with equip-
ment that lifts one or more of the wheels com-
pletely off the ground, remove the SmartKey
from the starter switch.
!Please also note the information in the
section on towing (
page 517).
iThe activation threshold is defined by the set
suspension tuning (
page 286).
iThe third available level is the highspeed
level that is set automatically.

Open cover plate1 (page 319).
Push in cigarette lighter2.
The cigarette lighter will pop out auto-
matically when hot.
Take out cigarette lighter2.
Warning!G
Never touch the heating element or sides of
the cigarette lighter; they are extremely hot.
Hold the knob only.
Make sure that any children traveling with
you do injure themselves or start a fire with
the hot cigarette lighter.
When leaving the vehicle always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Unsupervised use of
vehicle equipment may cause an accident
and/or serious personal injury.
!The lighter socket can accommodate 12V
DC electrical accessories (up to a maximum of
85 W) designed for use with the standard “ciga-
rette lighter” plug type. Keep in mind, however,
that connecting accessories to the lighter socket
(for example extensive connecting and discon-
necting, or using plugs that do not fit properly)
can damage the lighter socket. With the socket
damaged, the lighter may no longer be able to be
placed in the heating (pushed-in) position, or the
lighter may pop out too early with the lighter not
hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12V DC elec-
trical accessories designed for use with the stan-
dard “cigarette lighter” plug type to the
12V power outlets (
page 322) in your vehicle
whenever possible.
!The cigarette lighter is not designed for use
with the electric air pump (
page 501). Use a
power outlet (
page 322) for electric air pump
operation.
iIf the engine is off, and the cigarette lighter
is being used extensively, the vehicle battery
may become discharged.

Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Light Truck Center
for information on the installation of an
approved external antenna. Refer to the

Warning!G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system,
possibly resulting in an accident and/or
serious personal injury.
Warning!G
Please do not forget that your primary
responsibility is to drive the vehicle.
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we
recommend that you pull over to a safe loca-
tion and stop before placing or taking a
telephone call.
If you choose to use the telephone
1 while
driving, please use the hands-free device
and only use the telephone when road,
weather and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile telephone while driving a vehicle.
Only operate the COMAND system
1 if road,
weather and traffic conditions permit.
